Abstract

Polymers with both a hydrophobic (repelled by water) and hydrophilic (attracted to water) ends form spheres known as micelles whenever introduced with water. Each polymer has an optimal micelle size that gives the polymer a wide range of properties. These properties range from being more bendable to being more elastic. This experiment used Poly-ethylene oxide-block-hexyl acrylate with the hydrophobic and hydrophilic ends in order to find its micelle size, which was done by adding multiple amounts of water and agitating the samples at different intervals. This experiment found that the micelle size of the polymer Poly-ethylene oxide-block-hexyl acrylate had a micelle size between 10 and 1000 nanometers, and that the micelle size can be found by adding some value between 20 and 100 microliters of hydrochloric acid.
